Expansion shell type anchoring head and anchor rod
The expansion shell type anchoring head is installed on a rod body with external threads when used, the expansion shell type anchoring head comprises an expansion shell inner wedge and a plurality of expansion shell clamping pieces, the expansion shell clamping pieces are attached to the expansion shell inner wedge, and a wedge face structure matched with the expansion shell inner wedge is arranged between the expansion shell clamping pieces and the expansion shell inner wedge. The expansion shell clamping piece is provided with a first end and a second end which are opposite in the axial direction, the expansion shell inner wedge comprises a first part with a wedge face structure and a second part with a supporting shoulder matched with the second end, and a center hole which is axially through and allows the rod body to penetrate through is formed in the expansion shell inner wedge. The inner wall of the center hole is provided with an internal thread matched with the external thread. The expansion shell type anchoring head is provided with the axial through center hole, the rod body can penetrate through the anchoring head, and then a plurality of anchoring heads can be installed.
本发明公开了一种涨壳式锚固头及其锚杆，所述涨壳式锚固头使用时安装在带外螺纹的杆体上，包括涨壳内楔以及若干涨壳夹片，所述涨壳夹片贴靠所述涨壳内楔，且两者之间具有相配合的楔面结构，所述涨壳夹片沿轴向具有相对的第一端部和第二端部，所述涨壳内楔包括带楔面结构的第一部分以及带与所述第二端部相配合的托肩的第二部分，所述涨壳内楔的内部设置有轴向贯通的可供所述杆体穿过的中心孔，所述中心孔的内壁具有与所述外螺纹相配合的内螺纹。本发明中涨壳式锚固头具有轴向贯通的中心孔，杆体可以穿过锚固头，进而可以安装多个锚固头。
